step

System object: comm.FMDemodulator
Package: comm

Applies FM baseband demodulation

Syntax

Y = step(H,X)

Description

Note

Starting in R2016b, instead of using the step method to perform the operation defined by the System object™, you can call the object with arguments, as if it were a function. For example, y = step(obj,x) and y = obj(x) perform equivalent operations.

Y = step(H,X) frequency demodulates an input signal, X, and returns an output signal, Y. The input X is real or complex and can be either a scalar or a column vector. Double- and single-precision data types are supported. The output Y is real and has the same data type and dimensions as X.

Note

obj specifies the System object on which to run this step method.

The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties (MATLAB) and input specifications, such as dimensions, complexity, and data type of the input data. If you change a nontunable property or an input specification, the System object issues an error. To change nontunable properties or inputs, you must first call the release method to unlock the object.
